4 p.m. SPC update: High risk still in effect

Convective outlook map showing slight, moderate and high-risk areas

The National Weather Service Storm Prediction Center (SPC) issued an updated Day One Convective Outlook at 4 p.m. EDT. The updated outlook continues to indicate a high risk for severe weather in the northern third of Indiana between 3 p.m. today and 8 a.m. tomorrow.

In the 4 p.m. update, SPC wrote that the threat for a significant, widespread damaging wind event still appeared to be on track from southern portions of the Great Lakes into the Ohio Valley region. Storms were in the process of developing from northeastern Iowa into southern Wisconsin. These initial storms might organize as discrete supercells with an initial tornado threat. Storms should eventually consolidate and transition to an organized complex of thunderstorms (mesoscale convective system), with an increasing threat of significant wind damage as it moves east-southeastward through the southern Great Lakes and Ohio Valley during the evening and overnight.
